Korg iPolysix, £22.99/$29.99

With the iPolysix Korg repeated the trick that made us fall for the iMS-20. Again, the developer gave us a faithful recreation of one of the company’s legacy synths and bundled it with a step sequencer, drum machine, mixer and effects.

Just as with its predecessor, the sound of the iPolysix is spot on, giving iPad users the sound of the classic polyphonic analogue synth.
